The ‘Friends’ actor died Oct. 28 at age 54.
Matthew Perry died from the acute effects of the anesthetic ketamine, according to an autopsy released on Friday by the Los Angeles County Medical Examiner’s office.
The results of the autopsy listed drowning, coronary artery disease and buprenorphine (used to treat opioid addiction) effects as contributing factors. The manner of death was ruled an accident.
“At the high levels of ketamine found in his postmortem blood specimens, the main lethal effects would be from both cardiovascular overstimulation and respiratory depression,” the report states, per CNN.
After Perry was found unresponsive in the hot tub at his Los Angeles home, the L.A. County Medical Examiner’s office completed an autopsy but listed the case as “deferred” on its website, before removing it completely.
